Reset Button

To reset to factory defaults, press and hold the

Reset button for more than 10 seconds while the PowerBeam
is already powered on. Alternatively, the PowerBeam may be
reset remotely via a Reset button located on the bottom of the
Gigabit PoE adapter.

Release Button

After you assemble the PowerBeam, check

the Release button; it should be fully engaged in the Release
Button Slot of the Rear Housing. This ensures that the Antenna
Feed is locked into place. If you need to remove the Antenna
Feed, you must depress the Release button first.

LEDs

Signal

In airOS, you can modify the wireless signal

strength threshold values for each LED on the
Wireless tab under Signal LED Thresholds. The default
values are shown below:

LED will light blue when the wireless signal
strength is above -65 dBm.
LED will light blue when the wireless signal
strength is above -73 dBm.
LED will light blue when the wireless signal
strength is above -80 dBm.
LED will light blue when the wireless signal
strength is above -94 dBm.

Ethernet

The Ethernet LED will light steady blue

when an active Ethernet connection is made and
flash when there is activity.

Power

The Power LED will light blue when the

device is connected to a power source.

Application Examples

The PowerBeam mounted outdoors with the Reflector
installed provides directional outdoor coverage (gain is
reflector‑dependent).

The PowerBeam mounted outdoors without the Reflector
installed provides outdoor‑to‑indoor coverage using the 3 dBi
Antenna Feed only.

Installation Requirements

• 13 mm wrench
• Shielded Category 5 (or above) cabling should be used for

all wired Ethernet connections and should be grounded
through the AC ground of the PoE.
We recommend that you protect your networks from the
most brutal environments and devastating ESD attacks
with industrial‑grade shielded Ethernet cable from Ubiquiti
Networks. For more details, visit www.ubnt.com/toughcable
